the mail.log shows: Oct 18 13:17:14 mail postfix/qmgr[7286]: warning: connect to transport private/amavis: Connection refused Oct 18 13:17:14 mail postfix/error[7546]: 0BA7416C3C92: to=<info@*.com>, relay=none, delay=3019, delays=3019/0.01/0/0.06, dsn=4.3.0, status=deferred (mail transport unavailable)
and the last one: Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty Server version 64b
Did you try to restart postfix as well? It might be tht this error occurred during amavis restart. Did you try to send a new mail?
Yes, already restarted postfix and amavis a couple of times. Just finished a server reboot. Also tried sending and receiving email. That's when the mail.log errors show up. ********** hold on. after the reboot, it seems to be processing and delivering new emails. But the old emails, since the update yesterday that are queued are giving mail transport unavailable: Oct 18 13:34:15 mail postfix/error[2675]: 0C13416C3C64: to=<info@*.com>, relay=none, delay=4492, delays=4492/0.02/0/0.07, dsn=4.3.0, status=deferred (mail transport unavailable)
Till, comparing the delivered emails with the undelivered queue: relay=none dns=4.3.0 relay=dovecot dns=2.0.0
forcing the re-queue seems to have fixed the problem. But not too confident, since I can't pinpoint the problem to start with
Same problem here : Mail stops to go out from server. Fix is to restart (or start, depending) amavis and then Postfix, and finally postqueue -f. Wheezy 64 / ISPC 3.0.5.4p3 The problem seems to happen more and more frequently : fine for a several weeks, two times since yesterday.
You should check your logs why amavis fails, the most likely reason it that it runs out of memory. Hardware failures are also a possible resaon for segfaults in applications.
Thanks. Turned out my problem was clam not started, because it wasn't in the starting services at boot. This explains the second failure. As for the first one, thd provider who hosts the VPS has had problem past week, so a reasonable guess is some that some of these problems impacted my server in a way or another. More generally speaking, I already installed munin which does a great job restarting failing services. I'm wondering if there is a way to be warned when postfix is still live but stops sending mails, for the present reason or another.
ok.. ubuntu postfix main.cf is: content_filter = smtp-amavis:[127.0.0.1]:10024 Server receives and send all new emails. But the queue emails are still stuck: error.... relay=none, status=deferred (mail transport unavailable) even after postqueue -f they show relay=none when it should be relay=dovecot
Ok conclusion so far. changing the main.cf to: content_filter = smtp-amavis:[127.0.0.1]:10024 instead of: content_filter = amavis:[127.0.0.1]:10024 Seems to have fixed the issue. I have done several reboots and so far all pids are up and running with server receiving and sending emails. The messed up queue could not be fixed with: postqueue -f It need a full requeue with: postsuper -r ALL Let's wait for patch 6
The amavis transport that ispconfig creates during initial install is: Code: amavis unix - - - - 2 smtp -o smtp_data_done_timeout=1200 -o smtp_send_xforward_command=yes but your transport seems to have the name "smtp-amavis" instead of just "amavis".
Mr. Till With all this affair I noticed some weird entries on my mail log. Literally every minute I have: connect from g158.green.fastwebserver.de[85.114.128.158] lost connection after EHLO from g158.green.fastwebserver.de[85.114.128.158] disconnect from g158.green.fastwebserver.de[85.114.128.158] Could this be some sort of hack trying?
I see, never suspected until I took a look at the official page: https://help.ubuntu.com/community/PostfixAmavisNew
